1 '0 all whom it may concern:

Be it known that I, WILLARD J. Goonrnnrow, a citizen of the United States, residing at Bentley Springs, in the county of Baltimore and State of Maryland, haveinvented certain new and useful Improvements in Machines for Making Cigar-Wrappersfrom Tobacco-Stems; and-Ido hereby declare thefollowing' to scription of the invention, such as will enable others skilled in the artlto which it appertains to make and use the same.

This inventionv has reference to the conversion of tobacco stems into cigar wrappers, and one of its objects is the provision of a machine by means of which tobacco stems may be converted into cigar wrappers having. the appearance of those wrappers made from the natural tobaccoleaf.

A further object of the invention is the provision of a machine of the above stated character by means of which tobacco stems may be formed into a continuous sheet or web in which the fibers are so arranged as to prevent ther tearing of the Web lengthwise during itspassage througlf the machine.

A further object of the invention is the provision of a machine of the above stated character which may be set up and operated in an ordinary pulp and paper mill, which will be comparatively simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost. 1

With the above and other objects in View, the invention consists in the construction, combination and arrangement of parts hereinafter fully' described and claimed, and illustrated in the accompanying drawings wherein: t

Figure 1 is a sectional view taken on a plane extending centrally and vertically through the front part of the machine.

be a full, clear, and exact de felt 18 in proper Fig.7 is a detail view and side elevation of one of the rolls for maintaining a film oi. uniform thickness of tobacco liquor upon the1 rolls used to apply the liquor to the web, 'an

Fig; 8 is'a detail planviewbf one set of the rollers used to support the web during its passage between the. liquor applying drums.

Referring to the drawings by reference numerals, and particularly to Fig. 2, 1 designates a tank which has its upper side fully open. The tank is divided up into a large front compartment 2 and small rear compartments 3 and 4 by partitions 5 and 6. The partition 5, which has its upper end flush with the upper side of thetank 1, terminates short of thsbottom of the tank to provlde an opening 7 which establishes communication between the compartments 2 and 3. The partition 6, which has its lower to provide an opening 8 which. establishes communication between the upperv ends of the compartments 3. and 4. A pulp vat 8 is arranged within the compartment 2.- The front wall 9 of the pulp vat 8 is spaced from the front wall of the tank 1 and its upper end terminates short of the upper end of the tank 1 to provide an opening 10 through which the pulp-flows into the vat. The lower end of the front wall 9 of the pulp vat 8, and the bottom wall 11 thereof. are curved and spaced from the bottom wall of the tank 1. The rear Wall 12 of the vat 8 is spaced from the partition 5. The walls 9, 11 and 12 of the pulp vat, together with the front wall and'bottom wall of the tank end flush with thebottom of the tank 1, terminates short of the upper side of the tank ti'ally U-shaped compartment about the pulp vat 8. A. making cylinder 12 of any well known type is journaled within the pulp vat 8 eccentrically with relation to the curved bottom Wall 11 of the vat. A couch roll 13 is journaled on pivoted arms 14. This roll is maintained in proper engagement with the making cylinder 12 through weights 15 which are adjustably mounted the medium of upon pivoted arms 16, these arms being con! nected to of adjustable links 17 A first felt 18 passes ers 19'and the couch rollers 19 may be about the guide rollroll 13. One of the tension through the me ad usted to maintain the I the arms 14 through the medium dium of a jack 20 of any well known con struction. The top run of this felt passes over a suction box 22 and between the first set of press rollers 26 and 27. The bottom run of this felt passes between sprays 23 and 24, is acted upon by a beater 25, and

passes over a suction box 21.\

' A second felt 28 passes over the up e1" tact with the bottom press roll 30 by weightsv 33. The weights are adjustably mounted onpivoted arms 34 which are connected to the arms 32 by adjustable links 35. A doctor 36, located in front of the upper press roll 31, is carriedby the arms 32. The bottom run of the second felt 28 passes'u-nder a suction bOXl 37 and engages the first, felt 18 directly beneath that suction box. This suction box is located in advance of the first set of press rolls 26 and 27, and it transfers the web from the first felt to the second felt. A jack 29 is connected to one of the guide rollers 29 and provides means by which the second felt may be kept in proper tension. Any suitable means, not shown, may be used for imparting motion to the first and second sets of press rolls and the first and second felts.

To prepare the tobacco stems for conversion into sheet tobacco, they are first boiled in water in any vessel, not shown, suitable for the purpose. The resultant liquor is drawn off, after which the stems are removed and converted into pul in any well known manner. The pulp is ed by means, not shown, into the compartment 4. It flows from this compartment through the opening 8 into the compartment 3, and it then flows through the opening 7 into the horizontal and vertical branches of the U-shaped compartment formed by the front, bottom and rear walls of the pulp vat 8 and the front wall and bottomwall of the tank 1 and the partition 5. The pulp then flows through the opening 10 into the pulp vat 8. The making cylinder 12 and the couch roll 13 may be rotated'in any well lmown manner, and theweb formed upon the cylinder during its rotation is picked up by the first felt 18. This felt carries the web over the couch roll 13, over the suction box 22,'and between the first set of press rolls 26 and 27.

At a point in advance of the first set'of press rolls 26 and 27, the second felt 28 picks up the web and carries it under the suction box 37 and between the second set of press rolls 30 and 31. The web 38 leaves the up per press roll 31, and is carried by anapron The pulp is, during its passage from the compartment 3 to the vat 8, agitated to set up therein forwardly flowing divergent currents. These currents cause the fibers to arrange themselves on the bias or angularly with relation to the longitudinal center of the machine. It will thus be apparent that the fibers in the web will be angularly related to the longitudinal ce'nter thereof and that the fibers of the various groups of fiber will be angularly related. In view thereof,

the web is of such strength as to prevent its tearing longitudinally during its passage through the machine. The making cylinder is provided with a screen 12 which is so formed as to emboss the web in a manner that the wrappers made therefrom will have the appearance of those wrappers made from the natural tobacco leaf.

As will be apparentfrom Figs. 2 and 5 the agitator comprises a shaft 40 and dia: metrically opposite blades or ribs 41. The blades or ribs are of angular formation with their apices directed outwardly so that they will form a diamond shaped figure in which the shaft 40 is diagonally, arranged. The agitator is rotated in the direction indicated by the arrow in Fig. 2 of the drawings very rapidly, and to permit of motion being im-. parted to the agitator the shaft 40 is provided with a belt wheel 42.

A trough 43 is located in the tank 1 in advance of. the pulp vat 8 to catch the pulp thrown out of the vat\by the rotation of the making cylinder 12. By reference toFig. 5 I of the drawings, it'will be seen that theintake pipe 44 of a rotary pump 45 is in communication with one end of the trough 43. The discharge of the pump 45 is in communication with the compartment 4 of the tank 1 through the medium of a-pipe, 46. All pu'lp accumulating inthe trough 43 is returned to the tank 1, and as the pump is 50 and 51 are of the usual construction and are rotated in the usual manner. One of the guiding rollers 52 is provided with a jack 53 by means of which the apron 39 may be kept at proper tension. The web 38- passes about the heatin roll'49 with the apron 39. After passing 'a out the heating roll 49, the web 38 passes between upper and lower coating rolls 54 and 55,. respectively, Thes rolls are rotated in any suitable manner and are adapted to coat both sides of the web 38 with tobacco liqnor. The Web 38 is supported at each side tobacco waste about an adjustable reel 59.

a pipe 63.

transverse center of the coating rolls 54 and 55 by angularly related rollers 56 and 57 which are shown in detail in Fig. 8 of the drawings. After passing over the rollers 56 and 57 located in advance of the coating rolls 54 and 55, the web 38 is carried by the apron 39 about the heating roll 51. The web 38 then passes over a spring supported roller 58 and thence The reel is slidably and rotatably mounted upon inclined supportsand it is rotated in a direction to wind the web thereon by the apron 39, it being held in contact with the apron by the weld 38. To prevent the reel 59 from moving ofi' of the support 60 when the machine is not in operation, stops 61 are provlded.

The liquor used to coat both sides of the web 38 is produced by the boiling operation of the tobacco stems, and it is fed to a pan 62 located above the coating roll 55 by The pipe is provided with valve 64 by means of which the supply of tobacco liquor to the pan 62 may be regulated and controlled. A pipe 65, to which is connected a plurality of valvednozzles 66, communicates with the ends of the pan 62. The liquor is fed to the coating rolls 55 by the nozzles 66. A roller 67 is journaled adjacent the coating roll 55, and it is provided with a compound spiral rib 68 which-contacts with the coating roll 55. The rib 68 extends in opposite directions from the of the roller 67, and it is rotated in a direction reverse to. the -direction of rotation ofthe coating roll 55, its function being to prevent excess accumulation of liquor upon the coating roll 55. The excess liquor is carried to the ends of the and above said sheet-coating rollers, and sheet-drying rollers below said sheet-coating rollers;
